Hi All,<br>
<br>
I presented yesterday at APRICOT about Open DNS Recursors running in<br>
operator networks and how these are a security risk and being used in<br>
attacks (Slides:<br>
<a href="http://www.apricot2013.net/__data/assets/pdf_file/0009/58878/tom-paseka_1361839564.pdfor" target="_blank">http://www.apricot2013.net/__data/assets/pdf_file/0009/58878/tom-paseka_1361839564.pdfor</a><br>
Video:<br>
<a href="http://apnic.adobeconnect.com/p73ylpva3oa/" target="_blank">http://apnic.adobeconnect.com/p73ylpva3oa/</a>)<br>
<br>
While Singapore is one of the better nations in terms of open recursors<br>
we've seen (104 as of today), I'd like to help inform the operators and<br>
clean them up.<br>
<br>
If you'd like to know the recursors we've seen in your networks, please<br>
email me and I'll share the IPs.<br>
<br>
Thanks!<br>

Tom,<br>
<br>
Thanks for your presentation. Very interesting indeed.<br>
<br>
Please send me the ip addresses for Equinix and Qala/M1. I will get Equinix<br>
team to work on shutting the open recursers down. And i will forward those<br>
from Qala to my contact in M1.<br>
<br>
Thanks.<br>
Cheeyong<br>

Hi Tom,<br>
<br>
I am not sure if there are any Singnet (AS3758) folks on this list. But you<br>
can pass me the list from Singnet, and i can get someone to forward to the<br>
right person to have them closed.<br>
<br>
THanks.<br>
Cheeyong<br>
